IMPROVEMENT I N LUBRICATING AXLES FOR VEHICLES.

Specification forming part of Letters Patent No. 122,374, dated January 2, 1872.

Specification describing anew and Improved Lubricator invented by J nssn S. EGGLESTON,

nals, and other frictional surfaces; and, it con-.

sists in an oil-chamber and plate with a tube and capillaryconductor or wick in the stationary frictional surface to be lubricated, the construction'and arrangement being as hereinafter more fully described.

In the accompanying drawing, Figure 1 represents a longitudinal sectional view of a carriage-axle and box provided with my improved Fig. 2 is a cross-section of Fig. 1 taken on the line 00 m. Fig. 3 is a perspective view of the plate and tube with the wick or capillary conductor.

Similar letters of reference indicate correspondin g parts.

In this example of my invention I. show my lubricator applied to a car'riageaxle; but I do not confine it exclusively to that purpose, but intend it for journals of shaftings and for all purposes for which it may be adapted.

A is the axle. B is the box. 0 is a chamber or cavity in the axle. D is a plate which is let into the axle so as to cover the chamber 0. E is a tube attached to and passing through the plate, in which is a wick or capillary conductor F. This wick extends down into the chamber G. The lubricating material is placed in the chamber, which, of course, saturates the wick; The end of the wick projects through the plate 1) and is in contact with the moving or revolving frictional surface or box of the axle, and oil is constantly raised thereby and brought in contact with the moving surface by capillary attraction, and spread throughout the box so as to lubricate the entire frictional surface. always be a small recess, g, (see Fig. 2,) where the oil will accumulate, and from whence it can return to the chamber 0 by means of one or more small holes through the plate or orifices h in the edges of the plate, as shown in Fig. 3.

I do not limit or confine myself to the precise form of the parts shown, nor to any particular purpose or application of the device. The axle or journal being properly secured at the ends of frictional surface the oil cannot escape or be wasted, and will be constantly circulating'in the box and lubricating the axles or journals with the use of a very small quantity of lubricating material.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The chamber C, plate D, tube E, and wick F, constructed and arranged substantially as and for the purposes described.

2. The recess 9 above the plate D and the orifice h in the plate, in combination with the tube E, wick F, and chamber 0, as and for the purposes described. I

The above specification of my invention signed by me this day of 1871.
